Introducing APIArc: every frontier model, one arc away

Shipping with LLMs today means juggling half a dozen provider accounts, SDKs, rate limits and invoices. Every new model launch adds another integration to maintain — and another thing that can fall over in production. APIArc collapses all of that into a single gateway: one endpoint, one key, every frontier model.

Drop-in with the tools you already use

APIArc speaks the API formats your code already uses, so adopting it is a config change, not a rewrite. Keep the OpenAI SDK you already ship — point it at the APIArc base URL and every model in the catalog is available through it:

from openai import OpenAI

client = OpenAI(
    base_url="https://api.apiarc.dev/v1",
    api_key=os.environ["APIARC_KEY"],
)

resp = client.chat.completions.create(
    # swap providers by changing this string:
    # gpt-5, claude-opus-4-6, gemini-2.5-pro, deepseek-chat, kimi-k2 ...
    model="claude-opus-4-6",
    messages=[{"role": "user", "content": "Hello"}],
)

Building with the Vercel AI SDK? APIArc plugs in as an OpenAI-compatible provider:

import { createOpenAICompatible } from '@ai-sdk/openai-compatible';
import { generateText } from 'ai';

const apiarc = createOpenAICompatible({
  name: 'apiarc',
  baseURL: 'https://api.apiarc.dev/v1',
  apiKey: process.env.APIARC_KEY,
});

const { text } = await generateText({
  model: apiarc('deepseek-chat'),
  prompt: 'Hello',
});

Change the model string and the same request runs on a different provider. That is the whole migration.

Official channels only

Every request runs through official provider channels — no gray-market relays, no resold quotas, no mystery middleboxes reading your traffic. What the provider ships is what you get, including streaming, tool use and the latest model snapshots.

Fast by default, built to stay up

  • Latency-aware routing — each call goes to the fastest healthy upstream, and responses stream straight through.
  • Health checks & automatic failover — one flaky upstream never takes you down; traffic shifts before your users notice.
  • Metering built in — per-key usage and spend are tracked in the console, in real time.

Simple, transparent pricing

You pay provider list prices from a single credit balance — no markups, no seats, no lock-in. Top up once and spend it across every model; auto-recharge keeps long-running agents from ever hitting a dead key.
